Objective:
To assess the long-term risk of developing dry eye disease (DED) in patients who have undergone gastrectomy compared to matched controls.
Key Findings:
- Gastrectomy is significantly associated with a higher risk of dry eye disease (DED) with an adjusted hazard ratio (HR) of 1.09.
- Total gastrectomy shows an even greater risk with an adjusted HR of 1.40.
- The association is most pronounced in patients aged 60 or older, males, urban residents, and lower-income groups.
- Colectomy does not show an increased risk of DED, with an adjusted HR of 1.00.
Interpretation:
The study suggests that alterations to the upper GI tract, such as those caused by gastrectomy, may have a more direct impact on ocular surface health compared to changes in the colon.
Limitations:
- The study cannot prove causality.
- Potential confounding factors may not be fully accounted for.
Conclusion:
Post-gastrectomy patients may require closer monitoring for dry eye symptoms, emphasizing the need for collaboration between ophthalmology and gastrointestinal surgery.
